Why Ceramic Substrates Are Key to Ceramic PCBs
The overall performance of ceramic PCBs largely depends on the substrate material they use. Compared to traditional organic substrates such as FR-4(Glass Reinforced Epoxy, G10/FR-4), ceramic substrates have significant advantages in several key performance aspects.
1. Excellent heat dissipation capability
Ceramic materials, particularly alumina (Al2O3) and aluminum nitride (AlN), have excellent thermal conductivity, efficiently dissipating heat during operation, reducing junction temperatures, and improving system stability. This characteristic makes it particularly important in power devices and high-power modules.
2. Stable and reliable electrical performance
The ceramic substrate possesses excellent insulation properties and dielectric stability, and can still operate reliably under high voltage and high-frequency conditions. It is an important foundation for the application of ceramic PCBs in the fields of power electronics and radio frequency.
3. Excellent high-temperature resistance and aging resistance properties
Ceramic materials can operate stably at high temperatures for a long time without aging or deforming. They are suitable for use in highly reliable automotive electronics, industrial control, and new energy systems.
4. Excellent dimensional stability
The ceramic substrate offers low thermal expansion and structural stability, meeting the demands of high-precision circuits and high-reliability packaging. It serves as an ideal substrate material for high-end ceramic PCBs.
The crucial role of ceramic substrates in ceramic PCBs
From a structural perspective, ceramic PCBs are essentially circuit systems constructed with ceramic substrates as the core carrier.
The performance of the substrate directly determines the heat dissipation capacity, electrical performance and service life of the entire circuit board.
At present, ceramic substrates have been widely applied in the following ceramic PCBs and related structures:
·DBC (Direct Bonded Copper) substrate
·AMB (Active Metal Brazing) substrate
·thick film / thin film ceramic circuit
·high power LED module
·IGBT and power module packaging
It can be said that high-performance ceramic substrates are the key foundation for achieving highly reliable ceramic PCBs.
